Abstract
The techniques currently available for estimating loads on a transportation network are presented. There include trip interchanges assigned to minimum paths, traffic diversion theories, capacity restraint, a multi-route probabilistic approach, and direct traffic estimation, as well as small area assignments using the newly developed "micro assignment, adaption of network methods, and other simulation techniques. Operational decisions such as the selection of zones and network, selection of network impedance values, and the trip loading-adjustment process are discussed.
